ROAD-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 621,3? 1, dated March21, 1899.

Application filed September 25,1897. Serial No- 652,963. (No model.)

To all whom it may concern:

Be it known that I, FRANK PHILIP, a citizen of the United States, and aresident of Stock port, in the county of Columbia and State of NewYork,have in vented certain new and usef Lil Improvements inRoad-Scrapers, of which the following is a specification.

My invention consists of improvements in the construction ofroad-scrapers, wherebyit is designed to provide simpler, cheaper, moreefficient, and more easily-operating scrapers, as hereinafterdescribed,reference being made to the accompanying drawings, in whichFigure 1 is a plan View of my improvedroad-scraper with a part inhorizontal section. Fig. 2 is a side elevation. Fig. 3 is a detail inplan View. Fig. 4 is a plan View in a folded condition for storingcompactly, some parts being omitted. Fig. 5 is adetail of one of thewheels in side elevation. Fig. 6 is a plan of the said wheel attachment,partly in horizontal section. Fig. 7 is a side elevation of a lateralcoupling-bar between the moldboard and the beam. Fig. 8 is an endelevation of the moldboard and a-platform for the driver to stand onwhen more weight is required on the moldboard, and Fig. 9 isafrontelevation of part of the moldboard with an extension attachment that isdesirable to employ in some cases.

A suitable metallic beam (1 is provided of similar character, as aplow-beam, preferably of channel-iron form in cross-section. About themiddle of its length it is mounted on a suitable standard 0, which atits lower end has the laterally-projecting axle d, on which acarrying-wheel e is pivoted, being confined thereon by one or morewashers fand a linchpin g, said washers preferably being secured so thatthe wearing contact is between them.

. One is made to turn with the hub of the wheel by the spur and notch ath, and the linchpin is notched into the other so as to prevent it fromturning. This provision is made in order that the wear, which isexcessive owing to the side thrusts on the moldboard, may be spent onthe washers, which can be readily renewed from time to time. a flange ifor cutting into the ground for a holding to resist the side thrust ofthe moldboard.

The moldboardj is a long plate shod with about without doing work.

The wheel has steel along one edge and is supported at an an gle offorty-five degrees to the beam and under the rear portion of the beamsuitably for gathering the plowed-up earth at its forward end andshoving it over into the roadway behind the wheel e. At the back of themoldboard asuitable distance from the forward end a metallic bracket isis attached, in which there is a vertical slideway groove Z, and in thisgroove there is a sliding plate 112, which carries an axle n, on whichthe small wheel 0 is mounted for carrying the forward part of themoldboard j when the machine is to be moved The sliding plate m has anupward extension 19, terminatingin the toothed sector q, in the axis ofwhich a hand-lever s is pivoted, said lever having alaterally-projecting arm 16 radial to the pivoto and at its outer endconnected bya rod to with an eye-stud a: on the bracket 70, so that whenthe lever is shifted to the left hand the wheel 0 will rest on theground and the moldboard will be raised above the ground, and viceversa. A pawl y locks the lever in the different positions. The pawl isprovided with the usual hand-lever z and spring a for controlling it.Near the other end of the moldboard it is provided with a socket b,fitted to slide up and down on a king-post c, pendent from the rear endof the beam at, and is connected by a chain d With the short lateral arme of a hand-lever f, pivoted at g in the axis of a notched sector It,said lever having a pawl 71 for locking the lever in the differentpositions in which it is to be set. The pawl t" is provided with theusual hand-lever] and spring is for controlling it.

The kingpost is clamped in a vertical groove in the side of the beam aby a cap Z and suitable bolts, said cap and the notched sector h beingformed in one piece for simplicity and economy of construction. It willbe seen that by shifting the lever f to the left hand the moldboard canbe lowered to its work, while the reverse movement of the lever willraise the moldboard out of action. Between the king-post and thecarrying-wheel e the beam is upwardly curved for free passage of thescrapings under it. To maintain the moldboard in the proper angularrelation to the beam ,the diagonal stay-bar m is employed to connect themoldboard in the vicinity of the wheel 0 with the beam a near andpreferably in advance of the point where the beam is mounted on thecarrying-wheel t'. This staybar is preferably connected detachabl y tofacilitate folding the machine compactly for storage, as represented inFig. l; but it may be permanentlyconnected, ifdesired. It may beconnected in various different ways, but in the plan herein representedthe forward end has a hook-head 91 inserted through a slot 0 in thevertical flange of the beam when presented with the bar swung wellforward of the normal position and adapted to have substantial holdingwhen said bar is returned to said position.

The rear portion of the stay-bar is bowshaped suitably to reach over thetop of the moldboard and down to a bearing-point behind for high rangeto clear the upgathered matters on the moldboard. A spur p of theforward face of the lower portion of the staybar rests on the upper edgeof the moldboard to maintain the proper altitude, and below said spursaid face is grooved 01' notched, as indicated at q, to engage with ribs8' to prevent upward escape of the bearing end under severe stresses. Ahorn n of the bracket 7c and the foot-piece of the bracket confine thestay-bar against escape from the ribs 8 either way laterally. It will beseen that these contrivances afford simple and reliable means ofdetachable connection of the stay-bar without bolts, hooks, or the likerequiring manip ulation.

It is at times desirable to have longer reach of the moldboard in thedirection for gathering the upturned soil, for which I attach anextension-plate 25 by lapping a portion of it behind the end portion ofthe main board and bolting thereat, as shown in Fig. 9, or in anyapproved way, said extension being preferably of less width than themain board, at least in the part projecting beyond the latter, toprevent overloading the moldboard when the quantity of loose-earth inrange of the extension is large.

The beam at is of channel-bar form for the most part of its length, withthe two flanges projecting sidewise, as will be understood by looking atthe sectioned part of the beam in Fig. 1; but in the part forward of thesection it also has a flange f at the lower edge on the opposite side tothe channel, which, together with the lower flange on the other side,has bolt-holes 10, preferably in the form of notches, in the edges forconvenience in form-.

ing them in the casting, and the tongue 4) is bolted onto the upper sideof flange f, as represented in Figs. 1 and 2, when two horses are to beemployed; but for a three-horse gear the tongue is detached, the twotransverse bars w are bolted onto the under side of beam, and the tongueis bolted onto the extremities of the bars to, as shown in dotted linesin Fig. 1 and shown in part in full lines in Fig. 3, the middle horsebeing then placed directly in front of the beam. The bars w are stayedby a diagonal brace 112 The evener-coupling jaws as are formed on theend of the beam. To prevent bolts .23 from working loose in the slotholes when the tongue is adjusted for two horses, the bars 20 areretained, as shown in Fig. 1, so that the bolts will oppose the tendencyof said bolts :0 to work loose.

A platform a is mounted on the back of the moldboard for the driver tostand on when it is desirable to add his weight for better effect. Theinner edge of the platform rests against the rear face of the moldboardabove the stiffening-flange b of the moldboard, and hook-stays 0 securedto the respective ends, engage with eye-studs (l of the moldboard for asimple means of detachably connecting said platform. The floor ispreferably of grating to allow matters thrust over the moldboard toescape.
